- SPRINKLER FOR IRRIGATING SXSTEMS.

T call whom/it may concern:

' Be it known that I, LON MORRELL, a citia specification;

This invention relates to sprinklers and in its more intense aspect to sprinklers particularly adapted for use in irrigating systerns, although it.may be used for other purposes if so desired.

One of the objects of the present invention is to provide a simple and practical sprinkler of the abov character adapted to elficiently and uniformly sprinkle or irrigate a predetermined surrounding area.

Another object is to provide a device of the above character having few parts which will be cheap to manufacture and install.

A. further object is to provide adurable sprinkler of the first abovementioned character' which will be positive in its'operatio'n and economic in use, the parts being so arranged and designed as to eliminate a wast of water when in operation.

Other obj ects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the analysis of this invention.

This invention a ccbrdingly consists in the features of construction, combination of parts, and in the unique, relations; i the members and in the relative'proportioning and "disposition thereof; all as morecompletelyzoutlined herein:

To enable others skilled in fully to comprehend the underlying features thereofthat theyf nay embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure,.and in such drawings, likecharacters of reference denote corresponding parts throughout all the views, of which Figure 1 is a side elevation of a single complete device; Fig. 2 is a bentralvertical sectional view of the'device shown in Fig. 1; Fig. 3 is a view similar to Fig. 1 taken at I right angles therto; Fig. 4.- is a view similar to Fig. 2 taken at right angles thereto; Fig. 5 is a sectional view'taken on the line 5--5 of Fig. 2. v

Application filed December 4 1914, Serial N 0. 875,472.

- 2 In order that the present invention may be more clearly understood, it is to be noted that the above mentioned drawings disclose only one of a plurality of devices of a similar construction adapted to be regularly disposed about an area to be irrigated in such a manner that each device will uniformly irrigate a circlesubstantially tangential to five or six circles-irrigated by similar devices thereabout. While it may have been attempted to employ rotary sprinklers of various types heretofore in irrigating relatively large areas, there may have'arisen the area inclosed thereby was hardly touched,

or if the intermediate area was irrigated by oscillating the sprinkling nozzle during its rotation, the center was irrigated to a wasteful degree due in part to the loss .of water used for operating the device.

The present invention is designed to overcome the above objections, among others, by

uniformly irrigating a predetermined area completely about the centrally disposed de-.

vice and to positively utilize all of the watei ynching the device, first, for positively revolving a sprinkling nozzle and, second for irrigating-4 the land after performing its driving function.

-Withthis preliminary sketch of the present invention in mind, attention is now directedto Figs.- 1 and .2 ofthe drawings 'wherein is disclosed one of the devices in This devicecomprises a coupling member 10 provided with a threaded end 11 for engagement with the upper part of a stand pipe (not shown) forming a permanent portion of the irrigating system. This coupling has av central inlet tube 12 upon which isswiveled a collar '13 having a connection with branch pipes 17 of acasting 15 provided at its upper part with an open. A ring is adapted toh'old the casing inplace upon the coupling and also prevent leakage.

The chamber 16 is provided with a cover 18 threadely connected therewithand pro- .vided with a central aperture 20 at which point is secured a"fiXed portion ofthe sprinkling head 21. This head has op'positely and horizontally disposed openings, inone of which is secured a rigid elboi x -device, the intermediate area'being similarly irrigated as the nozzle. oscillates from one z continuously turning the-latter, means benozzle- 22, and the opposite oneha plug 23 adapted to permit access .to the interior thereof as-for packing the connection f' This "nozzle 22 is so mounted as to turn about the horizontal axes of the openings in the -.Within the chamber 16 is positioned .a

v turbine 24, in order to obtain maximum efii: .ciency, adapted to rotate in a horizontal --more clearly in Fig." -A rotation ,of this turbine24, willrotate a central shaft26'v connected therewith and uponwhich is mounted a. worm gear 271- wormgear co-acts wlth an inclosed 1n1on 28, as shown morefclearly in Fig. 4. ccentrically mount-' swing theknozzle through the arc indicated by the -dotted lines in Fig.3 whereby aincoinbination; a-circular caslng-having an ed upon this pinion 28 atthe 'point'30is connected one end-of an intervening link 31,

the 'opposite'endofwhich is pivotally con- .nected at 32with a';lug-'33 upon the oscil-' lating nozzle 22;. It will thus be seenthat g asfthe gear or pinion 28 is rotated, the link.

31 willbe-alternatelyraised and lowered to stream of vwater'at uniform-pressure issuing from thls nozzle w1ll havea-maxnnum range when'lin substantially the dotted line po'sif Jtion; to reach the outer circumference of the circle to be irr-igated, while in the elevated positiongtlfe stream will be directed almost straight/ upwardly to fall in a. manner similar. to rain-relatively'close to the irrigating extreme to the other.

In order to positively rotate t'he device and irrigate the complete. circle "the stud I shaft 34 upon which the gear 28, ismounted projectsto one side and is provided withan eccentric 35 upon which ismounted' a pawl I 36. The lower end of this pawl co-acts with ratchet teeth 37 formed :on the upper part I designed to uniformly and completely irriof the coupling 10, thus at. every'revolution ofthegear, the pawl will be raised and depressedcto progressively advance the sprinkler 1 a predetermined amount. The

teeth of the ratchet divide the circle into a corresponding number of sectors, each of which-"is irrigatedfrom the-center to the outer edge of the circumference by a complete;oscillation of the irrigating nozzle- It ,is thus seen that the present device is gate a relatively large area depending, of

course, to some extentupon the head of 'water used. The entire amount of water passes completely through the device, first to rotate and operate the same, and second,

to'pefform its irrigating functions, thereby f positively eliminating any waste that, might occur by diverging a portion of the, stream to operate the device as it escapes;

What' I claim is:

'- The' device in question is simple and pracac'complish, among others, all of the objects i and advantages above set forth.

Without further analysis, the foregoing edge readily-adapt it for various applications without omitting certain features that, from the standpoint, of the prior art, fairly constitute essentialcharacteristics of the generic or spec fic aspects of this invention,

'and therefore such. adaptations-should and I are,in tended to be comprehended within the meanmg and range of equivalency of the following claims' j s .70 j will so fully reveal the gist of this in'yention that others canby applying current knowl- 'tical in its construction and is designed to 1.
